Why do I need copper?
Copper is a trace mineral found in
all body tissues. It helps the body absorb iron, helps regulate
and stimulate the brain, helps protect and support the nervous and
glandular systems, assists in forming muscle & bone, and assists
in the pigmentation of hair and skin.
What are some of
the signs of copper deficiency?
Too little copper can cause fatigue,
weak blood cells, impaired respiration, skin sores,and lack of hair
and skin pigmentation. Copper deficiencies are fairly rare, but
can be caused by megadoses of zinc or Vitamin C.
How much do I need
and should I supplement?
While a small amount of copper is essential,
this is a mineral that it is easy to get too much of. Large quantities
can be toxic. The RDA is 2000mcg, which can easily be obtained from
food.
Copper is antagonistic to zinc, which
means that if you have too much copper in your body, your zinc supplies
will be low (and vice versa).
Never take a copper supplement by itself,
unless a copper deficiency has been detected by your health specialist
and it has been prescribed. However, copper is usually present in
multi minerals. If you have reason to think you have a copper imbalance,
try and find a multi without copper.
How
would I know if I've got a copper imbalance?
Symptoms of copper overload include
fatigue, skin problems, anxiety, roller coaster emotions, insomnia,
yeast overgrowth, PMS, and immune system disorders.
Nutritionist
Ann Louise Gittleman found that an excess of copper was the cause
of chronic, unexplained fatigue in many of her patients. Some people
are unable to clear excess copper from their bodies and are prone
to copper overload. If you have chronic fatigue that has no detectable
cause, her book "Why
Am I Always So Tired?" is well worth a read. It
includes case studies, how to test for copper overload and how to
reverse it.
Most health professionals are only
trained to recognise copper overload in it's acute forms, when the
diagnosis can be confirmed by blood or urine tests. But lower levels
of copper/zinc imbalance, which can still cause ill-health, can
only be detected by a tissue mineral analysis, preferably using
a hair sample.
What other causes
of fatigue should I consider first?
Some other causes of fatigue include
: over work or overtraining, not enough sleep, inadequate water
intake, inadequate nutrition or inappropriate diet, food allergies,
blood sugar imbalance, metabolic disorders, anemia, low thyroid
function, immune disfunction, depression and heavy metal overload.
I believe that the popular diagnosis of Epstein Barr virus or glandular
fever is actually a symptom of immune disfunction, rather than the
cause of fatigue.
What foods contain
copper?
Copper is readily available in many
foods. The copper/zinc ratio is also important, especially for people
who have trouble eliminating excess copper. Note that many popular
diets (including high carb/low fat, vegetarian, vegan and macro-biotic)
emphasise high copper foods and can contribute to fatigue caused
by copper imbalance.

Excess copper intake can also result
from copper water pipes and cooking utensils, some of the new dental
amalgams, pesticides and other chemicals, copper IUDs, birth control
pills and other oestrogen medications.
